arrangements and details of construction as will more fully hereinafter appear.

In the drawings,-Figure 1 is a side elethe invention; Fig. 2 is a sectional plan view; Fig. 3 is a perspective view illustrating a detail of construction; Fig. 4 illustrates, a modification; Fig.5 illustrates the manner of connecting the seat covering to the frame; Fig. 6 is a fragmentary top plan view illustrating a modification; Fig. 7 is a perspective view of the structure shown in Fig. 6; Figs. 8, 9 and 10 illustrate another -modification; and Fig-ll-is a sectional View showing the modified manner of connecting the seat covering to the frame.

In spring constructions it is very desirable to have the frame carrying the springs so formed that it may be easily and cheaply manufactured and y t possess the desired strength and rigidity stresses to Which the seat is subjected. It is also desirable that the seat parts be such that they may be readily assembled. With the spring seat embodying my invention, not only may the parts be easily and quickly assembled, butthe strength and rigidity of the structure is materially increased over spring seats now in common use.

Referring to Figs. 1 to 3 inclusive of the drawings, A designates the-bottom frame of i the spring seat, B the top frame and C the springs having their opposite ends connected to the frames A and B respectively. The

connection between the springs and the frame B, for the purpose of this inventioncomprises an outer annular member D and cross members or bars E, the latter being to withstand the attached to the springs but in the structure illustrated in Fig. 2 not being connected to the member D. In the type of spring shown the frame members D and E are of channel shaped cross-section and are connected to the bottom convolution of the spring upon opposite sides thereof. The end members of the series of sp'rings are also secured to those portions of the annular member D that extend transversely to the members E. The connection between the frame members and. the springs issuch as to lock the conyolution to the frame member against turning movement. This is accomplished in-the arrangement shown in Figs. 1- to 3 inclusive by cutting away portions F and G of one of the transversely-extending flanges, as 'H, so as to permit a portion I of the convolution of the'spring to rest upon the base J of the channel and abut against the inner face of the other flange K. The cut-away portions form spaced shoulders or abuts ments L and M which engage the convolution at spaced points. In the form of the member E shown in Fig. 2, the intermediate portion N is then bent over the portion I to hold the convolutions in engagement with the spaced shoulders and the inner face of the flange K, as well as to secure the convolutions to the base J.

with cut-away portions or recesses 0 (Z to I ,receive the convolutions c of the spring.

' In assembling the structure shown in Figs. 8, 9 and 10 the recesses 0 (Z are formed there in and the flange astruck up from the bot- "tom and arranged to permit the com'olm tions of the spring to be inserted between it and the flange f of the channel member. The lip (his then bent over the spring. as shown in Fig. 8. In each of the spring constructions shown a portion of the convolution not only is secured to the base of the frame member, but is held against the inner face of the flange. The convolution is also clamped against the spaced abutments or shoulders and. as the corners thereof from, said 'fiange :having sp'acjed shoulders, and a spring having 'iI'COllVOlUiJlOIl resting upon the body portion and contacting with the spaced shoulders, said member having a portion engaging the convolution for securingthe latter to the body portion and also the rigidity and strength of the frame is increased.

When the outer frame member D is and M. as shown in Fig. 3. since this allows "formed of'channel cross-section, if desired 1 the lower edge T- of the seat cov'eringU may be clamped to the frame-by turning down the flange H. as shown in Fig; 5. When the lower edge of the covering is so anchored the f 'ame member B is preferably connected to -the 'convolutions of the prings by turning down-a part only of the portion of the flange H intermediate the shoulders L the part V intermediate the lips O'and P tobe bent over the lower edge of the covering U, as shown in Fig. 5. Instead of bending down the flange H, the flanges of the -channel outer member may be bent together to secure the loweredge ot the covering thereto. as shown in Fig. 11; In 1,2.1 the member is formed of heavy wire and the springs are secured to the member A through the mediumof cross holding the convolution in engagement with said shoulders.
